Filed: 1972-09-21
Abstract: 1393756 Curing resin reinforced mouldings KOPPERS CO Inc 21 Sept 1972 [29 Sept 1971] 43835/72 Heading B5A A glass fibre reinforced thermosetting resin rod, sheet or tube R is formed by drawing through a heated metal die 11 the reinforcements 6 which have been impregnated with the resin during passage through a resin bath 8, and heated prior to entry into the die 11 by passage between a preheater comprising spaced radio frequency electrodes 10, or a microwave oven. The bath 8 is provided with an aperture 9 for removing excess resin, and the die entry is cooled to prevent solidification of further excess resin which is collected at 14 at the entry to the die. The moulding R is drawn by endless belt mechanism 17 delivering to a cut-off mechanism, and cooled in passage through water sprays 16. The die 11 may be heated by electrical elements, or circulating oil, and cooled by circulating water, and may comprise a tube or a split die and may comprise a chromium plated forming surface. The radio or microwave heaters may be controlled in accordance with the temperature of the resin impregnated fibres measured, e.g. by an infra red pyrometer, between the heaters and the entry to the die. The die may also be mounted for displacement in the moulding direction, and against a spring beam 22, Fig. 2, along rods 18 so that an increased traction of the mechanism 17 resulting from too great a hardening of the resin upstream of the die, deflects the beam 22 to sequential actuate microswitches 24, 23, the switch 24 illuminating a signal lamp and the switch 23 cutting the power input to the preheaters. In the Fig. 5 embodiment, (not shown), impregnated fibres for a moulded strip are drawn from the impregnating bath through a spaced rod pair, and through a further spaced rod pair guide downstream of the radio frequency or microwave heater, a pair of fibrous mats for opposed surfaces of the moulding being drawn through impregnation baths and into the die also downstream of the radio frequency or microwave heater. The resin comprises polyester of ortho-phthalic or iso-phthalic nature, fire retardant resin based on tetrachlorophthalic anhydride, and resin based on ethylene, propylpropylene, dipropylene, and neopentyl glycol. The reinforcement comprises rovings, mats, or woven glass fabrics and, where the moulding includes fibres pre-bonded in a required spatial relationship, these are drawn into the die downstream of the preheaters, as in the Fig. 5 embodiment, to avoid softening of the binding agent thereby.

Title: Method of and device for pressure difference measurement
Inventor: CREHANGE GERARD
IPC: G01L13/04
Filed: 1965-10-19
Abstract: 1,064,889. Measuring pressure electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. Oct.19, 1965 [Nov.10, 1964], No.44228/65. Heading G1N. [Also in Division G3] Pressure differences are measured by a device in which the level of a liquid dielectric in a capacitor varies in dependence on the pressure difference, the voltage across the capacitor, after it has been charged by a constant current for a constant time, being measured at discharge and from this the value of the pressure difference deduced. In the embodiment, a liquid dielectric 40, Fig. 2, e.g. oil, is placed in a U-tube, comprising two arms 22, 24 connected by a passage 26. One arm 22 is connected through a bore 35 in a cover plate 32 to atmosphere pressure while the other arm 24 is connected to a second atmosphere which is to be compared with atmospheric pressure, e.g. a glovebox. A capacitor 10 is placed in the arm 22, its plates 42, 44 taking the form of concentric cylinders with the plates 44 connected to earth and the plates 42 to constant current generator (8), Fig. 1 (not shown). Small orifices 50 are provided at the top and bottom of the plates for the passage of oil or air to damp any oscillations of the oil. The current required for operating the device is supplied from a crystal controlled high frequency oscillator (4), Fig. 1 (not shown). The oscillator drives a marker (6) in the form of a pulse amplifier which converts the sinusoidal signal from the oscillator into narrow pulses having the frequency of the oscillator. The marker then keys the con-  stant current generator (8) which charges the capacitor with a constant current for a constant time at the frequency of the oscillator (4). At the end of each charging period, the voltage across the capacitor is measured by a detector (12), the voltage being inversely proportional to the capacitance of the capacitor and therefore to the pressure difference to be measured. If it is required to maintain the pressure difference within a given range of pressures; two reference voltages are used, corresponding to the maximum and minimum pressure differences allowed, with which the detected voltage is compared. These reference voltages may be supplied, for example by a generator (14) to a comparator (16) to which the detected voltage is also fed. When either limit is passed a transistor becomes conductive and activates a relay associated with a trigger (18), controlled by the comparator (16) which operates means e. g. a vacuum pump or a valve giving connection to the atmosphere, to restore the pressure difference to the desired range. Two other triggers can also be provided which operate alarm systems when the pressure difference goes out of the range of adjustable pressure differences.
